Title: Improvements in coin freed locks
IPC: G07F17/14
Filed: 1971-04-19
Abstract: 1,274,179. Locks. SCHLOSSFABRIK SCHULTE-SCHLAGBAUM A.G. 19 April, 1971 [10 April, 1970], No. 25881/71. Heading E2A. [Also in Division G4] A coin freed lock includes a catch 19, pivoted at 8' and engageable with its free end 19' in a notch 25 formed in the bolt 22 to prevent movement of the bolt to its locking position, the catch 19 being arranged to be moved out of the notch 25 by a coin 31 inserted into the lock so that the bolt can then be moved to its locking position by actuating a cylinder lock 9 with a first key, the lock also including a lever 17 arranged to be pivoted about 16 when the cylinder lock 9 is operated by a second (master) key so that arm 17" moves the catch 19 out of notch 25 and the bolt is moved to its locking position without inserting a coin. Coin action: The coin inserted at 28 is arrested in the position shown by a stop 29 and a pin 30, the latter normally projecting through a hole (not shown) in the bolt. Rotation of the cylinder of lock 9 by the first key acts through lever 13 and pin and slot 20, 21 to move the bolt and thus pin 30 leftwards, whereupon the edge of the coin frees catch 19 and keeps it clear of a notched profile 26, carried by the bolt. When the bolt reaches its locking position Fig. 3 (not shown), the coin falls between guides 39, 40 carried by the bolt and now positioned to the left of the position shown. The first key can now be withdrawn from lock 9. Reverse rotation of the cylinder of lock 9 by the first key restores all parts to their original positions and the coin falls through slot 41, e.g. into a collection box. The key cannot now be removed from the lock.  The second (master) key, Figs. 6 and 7 (not shown), is formed with a transverse projection (45') which pivots lever 17 anticlockwise to free catch 19 when the second key is turned. Coin rejection. If the inserted coil is too small, it falls between stop 29 and pin 30 and out of a rejection slot 42. If a damaged coin is inserted at 28 or if a correct coin is inadvertently inserted, it can be recovered if bolt 22 is in the position shown, by depressing a button (not shown) to move a plate 32 carrying the pin 30 against the action of a spring 33, thus moving the pin 30 to an inoperative position allowing the coin to fall from the position shown. This imparting of movement to the pin 30 is prevented if the bolt 22 is in its locking position. Broken keys. If a part of a key should break off within the cylinder lock 9, and the bolt 22 is in its locking position, the broken part can be pushed further into and out of the back of the cylinder, through an aperture 47 in the bolt and out through a hole in the back plate of the lock casing, Fig. 5 (not shown). If the bolt is not in its locking position, the lock must be disassembled to push the broken part from the back of the cylinder out of the front thereof.

Title: Radio transmitter-receiver tuning system
IPC: G01S13/76
Filed: 1956-08-24
Abstract: 798,405. Combined radio receiving and transmitting systems. STANDARD TELEPHONE & CABLES, Ltd. Aug. 24, 1956 [Aug. 29, 1955], No. 25962/56. Class 40 (5). A tunable transmitter-receiver co-operating with fixed tuned transmitter-receivers 2, 3 and 4 in a radio distance and bearing navigation system, comprises a crystal-controlled superhet receiver 5, and coupling between the receiver and the transmitter 6, which are coupled to a common antenna 8, the transmitter frequency differing from the receiver frequency by the image frequency of the receiver. The pulsemodulated transmitter radiates pulses of a unique pattern determined by an unstable pulse generator 19. When the transmitter tuning is at the image frequency of the receiver, transmitter pulses pass through the receiver whose I.F. and discriminator circuits are tuned to select a frequency equal to half the image frequency and are applied to a coincidence gate 16 together with pulses direct from the pulse generator 19. The coincidence of the pulses produces an output which operates the " On Frequency Indicator " 23 to give an indication that the transmitter is at the image frequency of the receiver. The coincidence gate serves to prevent external pulses, from a ground station, producing a false indication.

Title: Improvements relating to spring balances or weighing machines
IPC: G01G3/04
Filed: 1933-09-21
Abstract: 427,390. Spring balances. SALTER & CO., Ltd., G., 144, High Street, West Bromwich, and WYATT, F., 42, Camp Lane, Handsworth, Birmingham. Sept. 21, 1933, No. 26058. [Class 143] In a spring balance or weighing-machine the indicator 6 is operated by two or more racks 8, 9 which come successively into operation so as to actuate respectively toothed indicator wheels or segments of different diameters or sizes the arrangement being such that the indicator moves through a greater distance (thereby giving a more open scale reading) for a given movement of the scale pan when a smaller wheel or segment is actuated than it does when a larger wheel or segment is actuated. In the example shown, the graduated portion of the dial scale up to two pounds is substantially twice as open as the graduated portion for the subsequent pounds, thus enabling the weight of relatively light articles to be ascertained with accuracy. The racks may be formed on a single bar or on separate bars. The arrangement shown may be modified so that the indicator is actuated by the larger pinion first, the final movement being effected through the smaller pinion. The tare reading may be eliminated by raising the upper end of the weighing spring 5 by means of a bellcrank lever 14 and an adjusting screw projecting through the casing.

Title: Improvements in or relating to two-way telephone and like transmission systems
IPC: H04B3/20
Filed: 1937-10-05
Abstract: 503,418. Two-way transmission. STANDARD TELEPHONES & CABLES, Ltd., MEERS, R. A., and THOMAS, P. R. Oct. 5, 1937, No. 26962. [Class 40 (iv)] [Also in Group XL] The attenuation due to an element or network of elements of non-linear resistance material in one transmission path is increased to disable the path by control voltage derived from signal currents in the other path and the application of the disabling voltage is prevented when signal currents are passing over the first path, the other path being substantially unaffected by control or disabling voltages. Specification 354,790 is referred to. In the arrangements shown in Fig. 4, a network X normally providing an anti-singing loss of 10 db. is inserted in receiving path B and a network Y of normally negligible loss but capable of providing a disabling loss of 70 db. i, inserted in the transmitting path A. Received signals cause suppressor S to apply control voltage to both networks so that the loss due to X is negligible and that due to Y prohibitive. Transmitted signals operate the suppressor disabler SS to prevent lock-out on a long 4-wire circuit the distant end of which is similarly equipped. Attenuators comprising metal rectifiers operate best at low levels and for this purpose a 20 db. pad G is arranged at the input to X, the resultant loss and the minimum loss due to X being compensated by amplifier E which also blocks the path to speech from line C. Attenuator X may be in the input to amplifier A1 to avoid the use of pad G. In modified arrangements, suppressor S is connected between the hybrid coil and balance network and the suppressor disabler is connected to the input side of pad Y thereby enabling the party on line C to break in on the distant party. Echo-suppressor S. A high impedance input is provided over resistances R1, R2 and condensers C1, C2 to reduce bridging loss. The input is amplified at V1 and rectified at voltage doubler X2 to apply negative bias to valve V2 which comprises one arm of bridge R5-7 and is normally of low impedance, the normal potential across diagonal m, n being such that pads X and Y have maximum and minimum attenuation respectively. When signals over path B increase the impedance of valve V2, the control potential across m, n is' reversed and reverses the condition of pads X, Y. The input to the suppressor is limited by a rectifier bridge XI normally polarized to a small loss condition. When the output from valve V1 exceeds a certain level, rectifier bridge X3 normally polarized to an inoperative condition feeds back rectified current to X1 to reduce its shunt impedance. The hang-over time is determined by condenser C7. Suppressor-disablor SS. This is substantially the same as the suppressor with the control bridge R5-7 omitted. Signals over path A result in a voltage across resistance R9 which paralyses valve V1 of the suppressor.

The inner container is divided into compartments by perforated discs 20, 22 on a tubular member 9 which abuts, at its inner end, the disc 26. The compartment 16 houses solid carbonate and a frangible acid bottle 11, which is located between a perforated tube 14 and a plug 12 in the member 9 The compartment 18 is packed with filtering material to prevent the passage of free acid. A plunger 28 slidable in the cap 5 has means, such as a groove and spring ring, for locking it in operated position, and has a'head 31 which co-operates with a seating 32 and washer 33 to act as a closing valve for the nozzle 34. When the plunger is driven inwardly, the inner container is moved until the disc 26 is ruptured by a stud 8 and the bottle 11 is broken by the plug 12. Dry gas then escapes by the port 25 to expel the carbon-tetrachloride through the valve 31 and through the nozzle 34. The extinguisher may be supported by resilient arms of a bracket engaging the plunger 28 and a handle 35. The reacting chemicals may consist of calcium or magnesium carbonate and hydrochloric acid, or potassium bicarbonate and sulphuric acid.
